| 摘 要： | 通过对天然径流小区的观测试验,研究了坡度、坡长与水土流失间的关系。结果表明试验区径流冲刷量、养分流失量、农作物产量与坡度和坡长存在着密切的关系。同时对该地区水土流失的成因进行了一定的分析,并提出了一系列水土流失防治措施,以便为当地的水土流失整治工作提供一定的科学依据。

| Abstract: | This article adopts the test procedure of runoff plot,and studies the degree of a slope and the slope length and the relation of soil erosion.The result indicates that the runoff of test area erodes and nutrient running off capacity and crops give birth to condition and output living forever at the close relation with the degree of an incline and slope.We also carry on certain analysis to this area for soil erosion origin,and a series of water and soil loss preventing and controlling measure are put forward,which will provides certain scientific basis for the local soil erosion improvement work. |
